Be it known that I, WILLIAM LoUDEN, ofthe township of Cedar, county of J efierson, State of Iowa, Fairfield 'bein g my post oiiicefhave invented-a new and usefnlllmprovement in Elevators; and I do herebydeclare l' Figures 2 and 3 refer to parts to be` expained here-Y "Similar letters of reference indicate corresponding.

l parts.

' This invention relates to certain improvements of the patents 4issued to vme :September 24, 1867, and March 17, 1868,' numbered, respectively, 69,107 and 75,686.

To .enable :those skilledin theart to make and use i ;my.-improvements, I will proceed to describelitsconstruction and operation.r y A y i A is an elevated .Y track or railway attached to the e ridge-pole U, provided with a canier,`B, hoisting-rope H, Sie; &c., substantially asset forth in the abovementioned patents. Y.

My first improvement consists in an improved method of attaching the track or railwayto the rid ge-pole, where by the track` can be suspended inits proper position without ascending into the peak of the barn. The bar N is placed inthe angle where the rafters R join, so that its ends will project beyond theiafter or rafters to which it is attached. It isheld in this position by pieces O fastened to the mters below it, or by other suitable means.

Fig. Zshows a cross-sectionofthe arrangement. The

ropeJ, which sustains .the track, is tied so as to form a loop or ring. This loopis passed overI the p projecting point Yof the barN'nntil itpassesbeyond the pro-v jection X. Enecessama guysrope, T, may be used.y

This arrangement can be used-to sustain either one or both ends. v

, My second improvement consists in' an improved A. method of attaching the horizontal pulley E to the track, whereby a common pulley-block can be used, instead of one made specially for the purpose,`as set y forth inmy patent of September 24, 1867. Itis attached directlybeneath the track, by means of a'single bolt passing up through a portion of the track, as sh'own in the drawing. By this means' the pulley is free to a follow the line'of draught, as shown at g. 3', and 4when not required in this position, can be used as an ordinary pulley-block. Fig. 3 shows a top view of the arrangement. y

My third Iimprovement consistsin providing the ad- ,justable stopv P with a projecting pin, g, around which the-hoisting-rope is fastened, as shown in the drawing..

This projcting point may hev made in the shape of a hook, so as to prevent the stop P from slipping in either direction.

holding the carrier stationary while the load is being i, elevated, and it consists in so. arranging the latch that j it may also be usedas a braketo prevent .the hoistingropj; from passing over the 'pulleyD While the carrier is-traversing the' tracker railway. It also consists of .an improved method of releasing the latch, and of preventing the stop b from being knocked loose by the return-motion of the carrier.

L is a lever, pivoted between the side pieces of the carrier B, see patent No. 75,686, dated 'March 17, 1868,) so that the ove'rbalancingv weight of its outer vend will cause itsinner end topressagainst the lower edge of the track or railway A, and when its outer end is elevated, its inner end kwill press against the hoistingrope H,' which passes over the pulley D.

The lowerl edgeof the `track A is tted with a notch orcaix:h,-ra, into or behind which the 'inner endof the lever L Bts, and prevents the carrier from moving along the track. 4

Another lever, L', is pivoted to the slide e of the carrier, or to any suitable part ofthe The rope u, which bears the weight W, is attached to thisleve'r, near its centre;

o lVA stop or block, F, is attached to the side of the ,K is a keeper or guide,- attached to the side of the carrier, to prevent the lateral play of the` lever L. g

The levers L L are connected with each other by means of a rope, chain, or other connectingdevices, which will allow the lever L suicient' play for the purpose hereinafter stated.

The operation'is as follows:

The carrier'is back on the inack far enough to allow the slide e and stop b to be in contact, the fre-e end of the lever L to rest against the stop' F, and theinner end of the lever L to engage the notch or catch a. The load m being elevated by power'applied to the hoistingrope, the one edge of thetilting-plate S (se patent No.'

75,686) comes in contact with the lower part ofthe carrier, and the other edge comes in contact withthe on r en d of the lever L. 'lhe pressure of the plateS ag st the cuter-end of the lever L elevates it, and releases its inner end from the. notch or catch a, which unlatches thel carrier and allowsitto move along the track or `iail- -way.- Y

' As vsoon as the lever L' is moved away from the stop.

F, the power of the weight W, applied through the rope @@draws th'e free end `ofthe lever L back. The levers L Lbeing connected, and the free end lof the lever L' `being no longersustained, the power ofthe weight W passing either l'mckward or forward. l As soon' as the load is'deposited, 'and the elevating-power withdrawn,

j ing weight.

the weight W drnws the carrier back, when the free end of the lever L comes in contact with the stop F.. A part of the power of theweightis then sustained by the block' o'r stop Rand the remainder is exerted upon the ean'ier. This remaining power draws the carrier back until the end of the slide e comes in contact withthe stop b. Thus the levers L Lare brought closer tof gether, andthe rope or chain h, which oonnectsthem,

- is slackend, so as to allow the'. lever L suicie'nt playl for its inner'end to drop intothe notch or catch a, when it is ready .to repeat the operation. l,

The advantziges of this arrangement are many andv important` v First, it will he. observed that-the hoisting-rope does not pass through any portion of the latchilig-cppara/tus.

B57 this means the `vload .can be taken from a point at either side, and as high as the tinck itself', without the hoisting-rope rubbing against the latch, and unlatching it before the Aplate or stop S comes in Vcontact withthe Second,'the 4free endof the lever L' coming in con.

4 tact with the stop F bcforetlxe slide e comes against .the stops b, divides the power of the descending weight between'the stops F and b, thus preventing the stop b from being knocked Third, the

loose by the force o f the descend-v arrangement of the levers L L', stop Lastly,'the entire device and. inexpensive.
